Introduction This meter is designed for measuring and monitoring Radio–Frequency electromagnetic field strength. The meter is calibrated precisely over the frequency range of 10MHz~8GHZ. Simple a method of operation Press “power” button on.To change measuring unit (mV/m), push UNIT”button to change the unit.Electric field strength (V/m).Computed magnetic field strength (mA/m).Computed power density... -
Page 6: Fundamentals
Fundamentals Electromagnetic pollution This meter is used to indicate electromagnetic pollution generated artificially. Wherever there is a voltage or a current, electric (E) and magnetic (H) fields arise. All types of radio broadcasting and TV transmitters produce electromagnetic fields, and they also arise in industry, business and the home, where they affect us even if our sense organs perceive nothing. -
